Question
Since rolling friction is less than sliding friction, sliding friction is replaced with rolling friction in most machines using ball bearings.
Answer: Option A
:
A
The given statement is true. Ball bearings are used in many machines to utilize rolling friction instead of sliding friction between moving parts. Rolling friction is preferred as it is less in magnitude than sliding friction and henceimproves efficiency of the machine.
